Abstract (en)
[origin: WO2016064319A1] A method performed by a network node 110, for handling handover of a user equipment (UE) 120, wherein the network node 110 serves a first cell 130 comprising one or more UEs 120. When the network node 110 has detected that a Signaling Radio Bearer (SRB) is determined to be scheduled for a UE 120 in handover from the first cell 130 to a second cell 131, the network node 110 increases the number of OFDM-symbols included in a control region of a downlink OFDM-subframe sent in the first cell 130 in a Transmission Time Interval (TTI) related to the handover. By increasing the number of OFDM-symbols of the control region only during the handover, the physical downlink control channel (PDCCH) is spread in time into symbols not polluted by CRS symbols from neighboring cells. Thereby the number of unsuccessful handovers and lost service is effectively reduced.
